Abstract
A wiper device is located between a rear door and a rear window, which is opened independently from the door. An actuator having an output shaft is attached to the rear door. A power transmission unit includes a shaft holder attached to the rear window and a pivot shaft supported by the shaft holder. Before the shaft holder is attached to the rear window, a positioning mechanism fixes the position of the power transmission unit relative to the actuator such that the axis of the pivot shaft is aligned with the axis of the output shaft. Thus, the axes of the output shaft and the pivot shaft are fixed during the installation process. Therefore, no adjustment of these axis is required during installation.

A wiper device for wiping a window supported by a support, the wiper device being located between the window and the support, wherein the window opens and closes an opening in the support, the device comprising:
- an actuator attached to the support, wherein the actuator has an output shaft and a first coupler member attached to the output shaft, and the actuator pivots the first coupler member in a first angle range;
- a power transmission unit, the power transmission unit including a shaft holder attached to the window, a pivot shaft supported by the shaft holder and a second coupler member attached to the pivot shaft, wherein, when the window is closed, the second coupler member is coupled to the firs coupler member to transmit rotation of the output shaft to the pivot shaft;
- a wiper arm attached to the pivot shaft, wherein, when the actuator is activated with the second coupler member coupled to the first coupler member, the wiper arm pivots in an angle range corresponding to the first angle range;
- and
- a positioning mechanism, wherein, when the wiper device is installed, the positioning mechanism provisionally fixes the position of the power transmission unit relative to the actuator such that the axis of the pivot shaft is aligned with the axis of the output shaft, wherein the positioning mechanism is located between the first coupler member and the shaft holder to connect the shaft holder to the first coupler member.
A wiper device for wiping a window supported support, the wiper device being located between the window and the support, wherein the window opens and closes an opening in the support, the device comprising:
- an actuator attached to the support, wherein the actuator has an output shaft and a first coupler member attached to the output shaft, and the actuator pivots the first coupler member in a first angle range;
- a power transmission unit, the power transmission unit including a shaft holder attached to the window, a pivot shaft supported by the shaft holder and a second coupler member attached to the pivot shaft, wherein, when the window is closed, the second coupler member is coupled to the first coupler member to transmit rotation of the output shaft to the pivot shaft;
- a wiper arm attached to the pivot shaft, wherein, when the actuator is activated with the second coupler member coupled to the first coupler member, the wiper arm pivots in an angle range corresponding to the first angle range;
- and
- a positioning mechanism, wherein, when the wiper device is installed, the positioning mechanism provisionally fixes the position of the power transmission unit relative to the actuator such that the axis of the pivot shaft is aligned with the axis of the output shaft, wherein the positioning mechanism includes a movable member located on one of the actuator and the power transmission unit, wherein the movable member is movable between a first position, at which the movable member fixes the position of the power transmission unit relative to the actuator, and a second position, at which the movable member cannot fix the position of the power transmission unit.
A wiper device for wiping a window supported by a support, the wiper device being located between the window and the support, wherein the window opens and closes an opening in the support, the device comprising:
- an actuator attached to the support, wherein the actuator has an output shaft and a first coupler member attached to the output shaft, and the actuator pivots the first coupler member in a first angle range;
- a power transmission unit, the power transmission unit including a shaft holder attached to the window, a pivot shaft supported by the shaft holder and a second coupler member attached to the pivot shaft, wherein, when the window is dosed, the second coupler member is coupled to the first coupler member to transmit rotation of the output shaft to the pivot shaft;
- a wiper arm attached to the pivot shaft, wherein, when the actuator is activated with the second coupler member coupled to the first coupler member, the wiper arm pivots in an angle range corresponding to the first angle range;
- a positioning mechanism, wherein, when the wiper device is installed, the positioning mechanism provisionally fixes the position of the power transmission unit relative to the actuator such that the axis of the pivot shaft is aligned with the axis of the output shaft;
- and
- a holding mechanism, wherein, when the positioning mechanism fixes the position of the power transmission unit relative to the actuator, the holding mechanism resists axial movement between the power transmission unit and the actuator.
A wiper device for wiping a window supported by a support, the wiper device being located between the window and the support, wherein the window opens and closes an opening in the support, the device comprising:
- an actuator attached to the support, wherein the actuator has an output shaft and a first coupler member attached to the output shaft, wherein the actuator pivots the first coupler member in a first angle range, and where in the first coupler member includes a first engagement member, which is radially spaced from the axis of the output shaft;
- a power transmission unit, the power transmission unit including a shaft holder attached to the window, a pivot shaft supported by the shaft holder and a second coupler member attached to the pivot shaft, wherein the second coupler member includes a second engagement member, which is radially spaced from the axis of the pivot shaft, and wherein, when the window is closed, the first and second engagement members are engaged with each other to transmit rotation of the output shaft to the pivot shaft;
- a wiper arm attached to the pivot shaft, wherein, when the actuator is activated with the first and second engagement members engaged with each other, the wiper arm pivots in an angle range corresponding to the first angle range;
- and
- a positioning mechanism, wherein, when the wiper device is installed, the positioning mechanism provisionally fixes the position of the power transmission unit relative to the actuator such that the axis of the pivot shaft is aligned with the axis of the output shaft, wherein the positioning mechanism is located between the first coupler member and the second coupler member to connect the second coupler member to first coupler member, and wherein the positioning mechanism is radially spaced from the axis of the output shaft and the pivot shaft and is spaced from the first and second engagement members.
